/**
 * Generates an interface with integer constants (hashed keys or simple sequence) to be used to get resource values.
 * saves ram-space using integers instead of full string keys. provides type-safed access to property values.
 * 
 * ON CONSTRUCTION:
 * 
 * 
 * - (generate key/values to property file (from bean-attribute informations))
 * - load key/values from property file.
 * - map them into a Map[Integer, Object] where the integers are the hashes of the keys. 
 * - generate an interface for that property file with: 
 *   public static final Integer [key-as-constant-name]=[hash(key)];
 *   
 *   These constants can then be used to get the mapped values:
 *      myresourceBundle.getString([generated-interface].[key-name-as-constant-name]);
 *
